, Application filedOctober 8, 1920. Serial-No; 415,587.

T 0 all wi wm'izf may concern; Be it known thati, FRANK Mossnnne, a

citizen of .the United States, residing at.

Attleboro, in the county of Bristol and State o't- Massachusetts, have invented certain new and useful Improvements in Beam Heads, of which the following is a specifi cation. I

This invention relates to an improvement 10 in the construction or" beam-heads in'which the head is adapted to be adjustably con nected to a beam on which yarn or other. material maybe wound, and the object of this invention is to provide a; head for beams of this charaoterwhichispreferably constructed of sheet metal and which is provided with .a hub-member adapted to 'be readily contracted to bind the head in adjusted position Upon the beam.

The nature'and advantages of the invention will be better understood when the following detail description is taken in connection with the accompanying drawings, the invention residing'in the combination and arrangement of parts as claimed.

In the drawings forming part or" this specification, like numerals of reference indicate similar parts in the several views and wherein Figure l is a side elevation illustrating my improved beam-heads as applied to the ends of a beam.

Figure 2 is an end view of my improved beam-head.

Figure 3 is a section on line 3'3 of F igure 2 illustrating the clamp by which the hub-section is adjustably connected to the head-plate. lVith reference to the drawings, 10 desig- 40 nates the usual body portion of a warpbeam which in this particular case is usually constructed of wood, but which, of course, may be made of any desired ma terial.

In the making of a beam of this character the head members 11 are preferably 50 constructed that they may be adjusted along the length of this body portion so as to regulate the working Width of the beam.

It is also one of the objects of this invention to construct both the head-plate and the hub-portion of sheet metal whereby the head may be very light in weight and the hu s t cic ly y cld lc a e ea y coir tracted: to, clamp the. same upon body portion and hold-the head. in any adjusted 7 position thereon.

The following is a detailed description of one construction OflMHlIll'llGflCl by which this result may be accompl1shed.:.

The main plate/l2 of this head 1s preferablyformed of sheet metal and its pe-- ri-pheral edge is bent. or folded to provide a stiffening flange 1S and the center of this plate is usually cut out as at 14 130 permit the passage of'the beam or body portion" therethrough. A hub member 15 is connected to the outer'face of each of these plates, which hub is preferably formed of sheet stock usually of a greater thickness than that of the head-plate, and thishub is preferably made in four sections 16, the ends 17.0f each section being bent to extend outwardly providing radiating arms, the outer ends of theadjacent arms of the, adjacent sections being turned inwardly and are fulcrumedone against the other, and the inner portions of these adjacent arms are nor.

mally spaced apart as at 19 and a bolt 20 is passed therethrough and the nut 21 when set up draws the adjacent sections toward each other causing the hub sections to con tract-about the body 10 to grip and bind the same and hold the head thereon in adjusted position.

The middle portion of each hub section is adjustably secured to the head-plate by the clamp member 22 which is shown in Figure'3, the neckportion 23 or" which extends through the corresponding opening through the sidewall of the hub, and the body of this clamp is riveted as at 27 to the head-plate thereby permitting the hub-section to slide radially thereon.

The outer ends of thesera-diating arm members 17 ma 1 be connected to the headplate by means of bolts 25 if desired or in some cases, particularly where the headplate itself is split as at 26, the arms 27 on oppositesides of the split portion may be connected to its section of the plate by rivets 28, whereby the head-plate itself may be slightly separated if desired'therebyprovlding a greater range of adjustment whereby the head itself may be contracted about I on each part of the plate to hold the plate sections in alinement or in the same plane with each other. 7,

By the use of my improved construction of beam-head, I am enabled to do away with the usual heavy and cumbersome cast-iron hub which heretofore has been employed for 7 this purpose and have provided one which is much lighter 1n weight, less expensive to construct, is stronger, and more durable and by its use this hub may be readily contracted to a comparatively increased extent to grip and bind the body portion of the beam and hold the head in adjusted position thereon.

The foregoing description is directed solely towards the construction illustrated. butv I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims. 7 r

I claim: r

1. A beam-head comprisinga'main diskplate, a contractible hub member comprising a plurality of sections each formed of a strip of yieldable material set edgeways against said plate and adjustably connected thereto, each section of said hub member being provided with a pair of radiating arms one at either end thereof fulcrumed at their outer ends and normally separated at their inner ends, an independent member on said plate intermediate said arms adjustably connecting each strip segment to said'plate, and means acting on said arms to contract sald hub about the beam.

2. A beam-head comprising a main diskplate, a sectional contractible hub member adjustably connected to said plate, said hub comprising a plurality of sections formed of a strip of yieldable material set'to slide edgeways on said plate, each section of said hub being provided with a pair of radiating arms, the adjacent arms of the adjacent sections being fulcrumed at their outer ends and normally spaced apart at their inner ends, means located intermediate said arms for adjustably connecting the different sections to said plate, and a bolt mounted to act upon and move said arms to contract said hub about the beam. 4 1

3. A beam-head comprising a main disk plate formed in sections, each section being. formed of a strip of yieldable material set edgeways to slide on said plate and each having a pair of radiating arms and adjustably connected to said plate sections, clamping" means in said arms for contracting both.
